SPECIFICATION forming part of Letters Patent N 0. 662,583, datedNovember 27, 1900.

Application filed September 24,1900. serial No. 80,896. lllo model.)

To all whom it may concern:

Be it known that I, FRANK THEODORE WIL- LIAMS, a citizen of the UnitedStates, residing at Meriden, New Haven county, Connecticut,

have invented certain new and useful Improvements in Lamp-Burners, ofwhich the following is a full, clear, and exact description.

My invention relates to oil-lamps of the central-draft type, andparticularly to the burner construction thereof.

The chief object of my invention is to prevent unsteadiness orflickering of the flame. This I accomplish by means which cause the gasand the air to be mixed uniformly and in the most effective proportions,which when lighted produces a flame of a steady character and ofpractically uniform height entirely around the burner. Incidentally theconstruction is such that the wick cannot be raised to an unnecessary ordangerous height. In addition to the foregoing features the constructionis such that the user can quickly extinguish the flame.

In the drawings, Figure l is a vertical section and elevation of alamp-burner of my improved construction. Fig. 2 is a plan view of one ofthe details of construction, one side of the same being partly brokenaway and shown in section.

A is an outer wick-tube. B is an inner wick-tube. C is a wick movablebetween said tubes, which wick may be raised or lowered by means of anywell-known wick-lift device. (Not shown.)

D is a flange or guard resting upon the top or upper edge of the wick C,which flange or guard is perforated or slotted, as at D, for the purposeof afiording a gas opening or space adjacent the inner side of the wickC. D is a cylindrical wall projecting downwardly from said flange D andhaving at its lower edge an inturned flange or supporting-ledge D Thecylindrical wall D is of such a size as to leave a space between itsexterior surface and the interior surface of the inner wicktube 13, sothat air flowing up through the tube B will pass up through the spacethus formed and supply air to the inner side of the wick when the sameis elevated, as shown in 'tinguished.

Fig. 1. To center the part D within the in net tube B, nibs or'bosses Dmay be provided, whereby the air-opening between the wall D and the tubeBis of a uniform size all around. Obviously the nibs D might be formedupon the inner wick-tube B instead of on the part D The shape of thesecentering-nibs is also entirely immaterial.

E is a perforated spreader, the lower edge of which rests upon thesupporting-shelf D so that when the wick is raised and lowered theflange D, cylindrical wall D and the spreader E will move together.

F is a stationary rod which projects upwardly through the top of thespreader and which carries a stop or cap G, which is preferablyadjustable, so that by its position the upward excursion of the wick islimited. In this way by adjusting the parts before using a person cannotelevate the wick to such a height as to cause the flame to smoke. Whenthe wick is lowered, the flange D practically covers the space betweenthe wick-tubes A and B, and consequently the flame will be ex- What Iclaim is- 1. In a device of the character described in combination, aninncrand an outer wick-tube forming between them a wick-passage, awickguard resting upon and supported by the wick, perforations in saidguard adjacent the inner-side of said wick, a wall depending from saidwick-guard said wall projecting into the inner who but of considerablyless diameter thereby affording an air opening or passage to the innerside of the wick, a spreader carried by said wick-guard, and means tolimit the upward excursion of said wick-guard and spreader.

2. In a device of the character described in combination, an inner andan outer wick-tube forming between them a wick-passage, a wickguardresting upon and supported by the wick, perforations in said guardadjacent the inner side of said wick, a wall depending from saidwick-guard said wall projecting into the inner tube but of considerablyless diameter thereby affording an air opening or passage to theinnerside of the wick, means to center said wall with respect to said innertube, a I00 spreader carried by said wick guard, and means to limit theupward excursion of said Wick-guard and spreader.

3. In a device of the character described in combination, an inner andan outer wick-tube forming between them a wick-passage, a wickguardresting upon and supported by the wick, perforations in said guardadjacent the inner side of said wick, a wall depending from saidwick-guard said wall projecting into the inner tube but of considerablyless diameter thereby affording an air opening or passage to the innerside of the Wick, means carried by said wall for centering the same withrespect to said inner tube, a spreader carried I5 by said Wick-guard,and means to limit the upward excursion of said wick-guard and spreader.

Signed at Meriden, Connecticut, thisl'ith day of September, 1900.
